LK 770 AeroSafe

The LK 770 AeroSafe is designed for air-water heat

pumps using R290 refrigerant. It removes liquid

refrigerant and non-condensable gases, protecting

the compressor and boosting efficiency. Made from

lightweight, lead-free stainless steel, it’s easy to

install and service with a removable lid. With a

flow rate up to 19.5 m3/h, low pressure drop, and

side discharge to prevent ice formation, it ensures

optimal performance and system longevity.

• Low pressure drop

• Lead-free

• Side discharge prevents ice formation

LK HydronicGroup C/C 125 Cooling is an all-in-one

pump group designed for both heating and cooling

applications. It includes a high-efficiency circulation

pump and insulation. The system offers two options:

direct supply with the LK 861 C pump group, or

mixed supply with the LK 862 C pump group, which

includes a three-way mixing valve. LK 862 Cooling

should be paired with an actuator, such as the LK

950 or 100 CT.

• For both cooling and heating applications

• Pipe is cataphoresis-treated to resist corrosion

• Easy to combine with electronic regulation
